If this does not work for you, take your MBP to the Apple Store, and let them deal with it. That's what the warranty is for. Take advantage of it, being that it is so new, it should be there problem, and not yours. Apple has been the leader in customer support, and I'm sure they will be able to make things right. All the best.
My new MacBook Pro doesn't pickup my wifi signal.
If your WiFi is WEP Encrypted then it won't, Apple is depreciating that in OS X as it's insecure by you thinking it's secure when it's not.
Also if your router has a "hidden" network, it won't reconnect automatically.
Also check the age of that router, it seems to be from China and I can't read Chinese, if it's not a Wireless N with WPA2 (AES) then I would get a newer one and update the firmware before using it.
Paste this command in Terminal and copy/paste the output here:
/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resource s/airport -s
Is your SSID/wireless network name listed in here ?
Can you log in to your router and make sure you are using channels between 1 and 11.
Does your Mac connect to all other wireless networks ? Is this issue only seen at home ?
